Kremlin waits for US probe in Russian boy's death

Kuzmina said she gave up drinking, had found a job and pledged to fight to get back Kirill.

Valentina Chernova from the children's welfare office said on the talk show that Kuzmina was stripped of custody for drinking bouts during her pregnancy and her negligence with her first-born.

The RIA Novosti and Interfax news agencies reported Friday that Kuzmina and her boyfriend, who were traveling Thursday night from Moscow to their home town, were taken off the train by police after a drunken brawl.

Peskov said a court will "take into account all the information about what kind of mother she is."
